Accidentally Knocked Laptop Off of Shtender - Must He Pay?

In this week’s episode, the topics discussed by Rabbi Braun include:Neder to Hear Kiddush Only from Husband: If a woman committed to hear Kiddush only from her husband, does she need hataras nedarim when that’s not possible?Does it make a difference whether the commitment was mental or verbal?Can hataras nedarim for this purpose be done on Shabbos?Transporting a Sefer Torah: May a Sefer Torah be taken out to a park for Krias HaTorah (e.g., for children to hear Aseres Hadibros)?Does having ten people walk along with the Sefer Torah make it permitted?What is the context of the Rebbe’s request for children to hear the Aseres Hadibros, and what is the proper way to fulfill it?Eruv Tavshilin: Can a person appoint a Rov through a phone system as his shliach to make an eruv tavshilin on his behalf in case he forgets?Does an eruv tavshilin need to be made with the person’s own food?Does the host’s eruv tavshilin exempt guests who are eating over but sleeping elsewhere?When do the guests need to be eating over to be included: on erev yom tov, on yom tov, or on Shabbos? What should the guests do practically?Kesubah Design: Is it proper to use the pasuk “Ani l’dodi v’dodi li” in a kesubah design?Are decorative pesukim on a kesubah appropriate in general?Is there a problem if the design makes the kesubah text hard to read?Responsibility for Breaking a Laptop: A person was stretching in a beis midrash and accidentally knocked a laptop off a nearby shtender: what factors do we account for to decide whether he must pay for the damage?Is a person ever not held responsible for absolute accidents?
